Abstract

The aim of the current study is to investigate the physicochemical parameters of three stations S1, S2, S3 that were selected on the Euphrates River at Samawa City, south Iraq. In addition, the density, distribution, and biodiversity of Copepods were investigated from March 2017 to February 2018. The recorded temperatures of the water were between 11.5–30 ᵒC. The densities of Copepods species were 1425 indv/m3. 841 indv/m3 and 1081 indv/m3 in stations S1, S2 and S3 respectively. And the highest density was recorded in S1, S3 during spring and autumn 2017.

The present study demonstrated that only Macrocyclops sp., and Halicyclops sp. were noticed at station S1, while mesocyclops leucarti., and Lernaea sp. were observed in S1 and S3. The most common genera were Cylops, three taxonomic units. Cyclops Scutifers and Cyclops Scutifers were noticed in all the study stations. Eucyclops, Paracyclops and Copepoda Naupli were observed in all station and the most common species in stations S1 and S3 were Diaptomus Franciscanus during. In contrast, only E. macrurus appeared only two times in the S3 station during this study. The current data found that the similarity between the three stations was 70%. And the lowest value of the qualitative deficit was 25% between station S1 and station S3. Suggesting that both station S1 and S2 environment is suitable for the availability of more species than stations S2. Also, this study noticed that the highest diversity of Copepods was recorded at the station n S1 in November 2017. While low Biodiversity was seen at all stations.
